This study examined whether previously reported effects of altered prenatal sensory experience on subsequent acceleration of intersensory development in precocial birds are mediated by mechanisms sensitive to the overall amount of stimulation provided.

Abstract
The mechanism of action of the auditory signal in increasing responsiveness to a visualβauditory stimulus in chicks of 14β48 hr was examined. Stimulus effectiveness of an auditory signal dissociated from the visual stimulus was less than proximate auditory signal presentation but greater than a silent visual stimulus. Familiarity with the auditory signal increased and decreased responding under proximate and dissociated presentation, respectively. These data were interpreted as confirming the influence of auditory stimulation via increased arousal, and as indicating the possibility of selective responding to specific features of the auditory stimulus when its localization at the visual stimulus is possible.

The fact that the sensory systems do not become functional at the same time during early development raises the question of how sensory systems and their respective stimulative histories might influence one another. Previous studies have shown that unusually early visual experience can alter subsequ
## Abstract The onset of responsiveness to eighth nerve stimulation was examined in n. magnocellularis and n. laminaris, (secondβ and thirdβorder neurons) of the chick brainstem auditory system. Extracellular microelectrode mapping techniques were used to examine postsynaptic responses in __in vitr
Neurotrophins and their cognate receptors are critical to normal nervous system development. Trk receptors are high-affinity receptors for nerve-growth factor (trkA), brain-derived neurotrophic factor and neurotrophin-4/5 (trkB), and neurotrophin-3 (trkC). We examine the expression of these three ne
The avian auditory brainstem nuclei nucleus magnocellularis (NM) and nucleus laminaris (NL) display highly precise patterns of neuronal connectivity. NM projects tonotopically to the dorsal dendrites of ipsilateral NL neurons and to the ventral dendrites of contralateral NL neurons. The precision of
